TIP-WAGON MECHANISM.

SPECIFICATION forming part of Letters Patent No. 746,541, dated December8, 1903.

Application filed August 3, 1903- Serial No. 168,057. (No model.)

To all whom it may concern:

Be it known that I, ALEXANDER MANSFIELD, a subject of the King of GreatBritain and Ireland, residing at Brunswick'street, North Fitzroy, in theState of Victoria, Commonwealth of Australia, have invented certain newand usefullmprovements in Tip-Wagon Mechanism; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

The object of'this invention is to provide improvements in tippingmechanism whereby the loaded vessel may be raised obliquely on eitherside of its support and tipped while be-.,

ing elevated to discharge the contents into or upon any suitablereceptacle, traveling belt, or receiver on either side of its normalposition.

The invention is more particularly applicable to wagons, in whichconnection I will describe the same; but it is obvious that it may wellbe adapted for cars and analogous means of transportation.

To more fully understand the same, reference is bad to the accompanyingdrawings, in which like characters designate like parts in the severalviews, and in which I Figure 1 represents an end elevation of a part ofa wagon containing my improvements;

Fig. 2, a reversed side elevation of the tipping mechanism and itssupport looking from the inside; Fig. 3, a detail fragmentary plan view,and Fig. 4 a detail view of the trunnionbearing and slide.

As each end of thewagon is provided with similar mechanism, I will forbrevity only describe the mechanism at one end thereof.

a indicates the tilting receptacle, 1) a bracket on the end thereof, andc a trunnion-bearing on said bracket.

0c is a suitable fixed frame having the downwardly-converging top faces0 and the centralcurved cut-awayclearance-spacey. Supported by thisfixed frame as is an adjustable frame comprising the rounded baseportion1 h, the arms h, and the upper cross-piece h suitably bolted to the armsh. These arms h are provided at their upper ends with cars from itsseat.

713, slotted, as at u, to aline when in position with correspondingslots 11. in the frame 00.

The outer face of the arms h and the base portion h are flanged, as atw, to form the channel h therearound, adaptedv to seat on the inclinedfaces 0 of the frame at, and are recessed at h h to engage the pins 8 son the frame 00, respectively, when the adjustable frame is shifted fromone side to the other and hold the base portion h against rising Theother end of the adjustable frame is held down on its seat by the pins15, passing through the slots 11. u.

e is a slide having its side faces channeled, as at f, adapted to engagethe inner faces g of the arms h and be guided thereby longitudinally ofthe adjustable frame.

The inner face of this slide-block e is provided with an elongated slotd, forming a ournal for the trunnion pin or bearing a, and

is internally screw-threaded centrally to receive an elongated screw '5,rotatably journaled at one end in the cross-piece b and carrying at itsother end the fixed bevel-gear j. Suitably journaled in the adjustableframe is the gear-wheel l, and alongside the same is located thebevel-geark, meshing with the bevel-gear j. p

m is a pinion meshing with a large gearwheel Z, the shaft of which isprovided with a crank it or other suitable driving means.

'1" represents bearers provided with the abutment-surfaces g, by meansof which the loaded receptacle is tilted and rests at different pointson the curved surface as the receptacle at is being elevated obliquely,the abutments q being located sufficiently inside-the plane 5 (parallelto screw 6) and acting as an obstruction to the rise of the interposedreceptacle on that plane. As the raising proceeds the angulardisplacement of the recepstops prevent displacement of the body duringhaulage. These are not shown or claimed.

In operating this invention power applied to drive pinion m ismultiplied by spur-wheel Z and conveyed by bevel-wheels 703' (where thepower is again multiplied when desired) to screw 1, which is thus turnedin its bearings, by which it is fixed in frame it, the screw therebyleading along its length slide-block e, (a worm through which the screwengages,) having trunnion-bearing d. The operator at one end may workfaster than that at the other, or one may work both body endsalternately, the trunnion-bearing (1 being made large enough to permitof one end of the body standing higher than the other. Means (not shownor claimed) maybe provided to secure body a temporarily at any desiredinclination, and abutments q may be adjustable or movable instead offixed. Any suitable means are provided to temporarily lock frame It inits inclined position on either of the converging faces 0. Preferablythere are at the base and at each side projecting flanges w, betweenwhich the sides 0 and frame w fit. Also stops 8 s and slots to areprovided at each side. Stops s s serve to restrain the lower end it ofthe adjustable frame from being lifted out upward, and when any suitablepins are passed through slots it into frame a: they prevent that end ofthe frame moving.

It will be observed that apertures u, u, and d are elongated and that inFig. 1 the upper ends of the slots are engaged by the pin 2i andtrunnion c,respectively,and in Fig.2 thelower ends. This is to allow theframeh to be lifted a little or made to slide upward (by a few turns ofthe handle n) off its seat on frame x at such times as said frame It isto be swung on its pivot 0. Thus friction is reduced. The frame m is cutaway at y to allow this clearance. When, however, the handle is turnedfor the raising of the body, the first effect is to lower frame It tillit sits solidly on frame w. This construction limits the strain of thebody a on the slide-blocks to such times as the raising is proceeding.The angle of the slot and the pitch of the screw within it, the sizesand number of teeth in the respective gear-wheels, and like details willdepend upon local circumstances.

What I claim as my invention, anddesire to secure by Letters Patent ofthe United States, is 1. In unloading mechanism, the combination withthe receptacle and a suitable support therefor, of means for obliquelyelevating said receptacle, and means for tipping the receptacle, whilebeing elevated,-transversely of said support and supporting the samewhile being elevated and tipped, comprising curved abutments adapted toengage the lower side faces of said receptacle.
